Specification of Letters Patent.

Patented March 23, 1909.

Application filed January 8, 1907. Serial No. 351,326.

To all whom it may concern:

Be it known that l, HANS LAMBERGER, a Subj ect ofthe German Emperor', and residing at 5 Bismarckstrasse, Leipzig, German E1npire, have invented new and uselul Improvements in and relating to Brewing-Machines, Powder-Machines, 'lalcing-Machines, Rubbing-Machines, Dusting-Machines, and Similar Machines.

The ob] ect of my invention is to make the dusting and rubbing ap aratus easily accessible. This is done f' arranging said apparatus in frames which are pivotally mounted on the frame of the machine so that the dusters and rubbers can be laid open vfor ins ection by tilting their frames.

leference is to be had to the accompanying drawings in which:

Figure 1 is a frontal view and Fig. a lateral vieiv of the machine, Fig. 3 is an elevation and Fi 4 a frontal view of a device ior regulating t e distance of the dusting rollers from the cylinder.

ln the frame C of the machine is arranged the cylinder l with the bronze-box m, the feeding device t and the rollers o o which. throw the nished sheets out oi the machine. A pulley 'l serves for acti'lating the Working parts. The casing of the machine is tightly closed so that no powder can escape. lf dcsirable, the powder is removed by a fan.

A is the rubbing apparatus. The rubbers H H arev arranged in a frame ivotally mounted on a fulcrum B. The ru bers are actuated in a Well known manner by means of a cam disk (shown on the left ol Fig. 2) and provided with connectingl levers and pull back springs. A cover D with a lock f closes the casing when the dusters are in. When they are to be cleansed or inspected the cover D is let down and the rubbing apparatus is bodily turned out. The dusting rollers l, 2, 3, 4 are also arranged in a traine. This frame, a, turns on a pivot c to which are connected a pulley s for imparting rotation to it from the pulley r and several other pulleys, one for actuating every dusting roller. The back of the casing a is closed by a cover l). A hook h holds the casing in the position shown in full lines in Which the rollers l to 4 are in contactwith the cylinder Z. W hen a sheet sticks in the machine or When the rollers are to be inspected, the hook 7L is taken oli and the casino o is let down.

lt is obvious from the foregoing that by the arrangement shown both the dusting and rubbing devices can be very easily cleansed or inspected, with very little loss ol time, and sheets, taken out, Without any demounting ol parts of the machine` Figs. 3 and Ll show a device for regulating the distance between the dusting rollers 1, 2, 3, Ll and the cylinder l. The shafts c of these .rollers are ilitted eccentrically into .bushes a, which are rotatably arranged in the lranie a, so that by turning the bushes the shafts c with the roller they bear can be approached to or removed from, the cylinder l. A slotted disk is attached to the outside of every bush uy and provided with a pointer y, which slides over a scale z, said scale being fastened on the [rame (1.. A screw '2.o passes tl'irough the slot in the disk u and through the l'irame a. The pointer y with the scale z renders it possible to adjust the bushes u very accurately. ri`he screw w serves for holding the disk u in the position chosen.

vWhat l claim and desire to secure by lietters Patent of the United States is:

l. ln bronzing machines, powder-machines, taleing-machines, rubbing-machines, dusting-machines and similar machines a frame, casings pivotally attached to said frame, and rubbing and dusting apparatus, said apparatus being arranged Within said 'pivotally attached frames.

In machines oll the class described a frame and a carrier pivotally attached to said frame, said carrier being adapted to receive the rubbing apparatus.

ln machines of the class described a lrame and a carrier pivotally attached to said haine, said carrier being adapted to receive the dusting rollers.

4. in machines of the class described a lranie, a carrier for the dusting rollers pivotally attached to said traine, bushes rotatably arrangei'l in said frame and adapted to rcceive the shafts of the dusting` rollers, the center of the shafts being at sonic distance lrom the center oi' the bush..

5. In machines of the class described a frame, a carrier lor the dusting rollers pivotally attached to said trame, bushes rotatably roo arranged in seid frame and adapted to l'el arranged in seid freine Lend adapted to receive 10 ceive the shafts of the dusting rollers7 the eeni the sl tts of the dusting Tellers, Ineens being tei of the shafts being at some distance from l provinod for holding seid bushes in position. the Center o' the bush, the bush being pioln testimony whereof l have hereunto vided with a pointer and the easing with a siguen my neme. seele under said pointei.
